This allows ftp-data and ftp flows to be processed by the same
thread. Otherwise, there may be a concurrency issue where the
would-be ftp-data flow is first processed, and thus not recognized
as such. And the ftp flow gets processed later and the expectation
coming from it is never found.
To do so, the flow hash gets used as usual, except for flows that
may be either ftp or ftp-data, that is either one port is 21, or
both ports are high ones.

This allows all traffic Exception Policies to be set from one
configuration point. All exception policy options are available in IPS
mode. Bypass, pass and auto (disabled) are also available in iDS mode
Exception Policies set up individually will overwrite this setup for the
given traffic exception.
Task #5219
As part of the process of moving documentation from redmine
to "Read the Docs", this commit moves installing Suricata using git
page from redmine wiki into Suricata Developer Guide section.
It also updates the necessary steps.
Ticket: #5585
This commit updates the bsize documentation
1. Describe what happens when "content" immediately precedes "bsize"
2. Include the operators and
3. Include examples using the operators.
with setrlimit NPROC.
So that, if Suricata wants to execve or such to create a new process
the OS will forbid it so that RCE exploits are more painful to write.
Ticket: #5373
This patch updates the NT status code definition to use the status
definition used on Microsoft documentation website. A first python
script is building JSON object with code definition.
```
import json
from bs4 import BeautifulSoup
import requests
ntstatus = requests.get('https://docs.microsoft.com/en-us/openspecs/windows_protocols/ms-erref/596a1078-e883-4972-9bbc-49e60bebca55')
ntstatus_parsed = BeautifulSoup(ntstatus.text, 'html.parser')
ntstatus_parsed = ntstatus_parsed.find('tbody')
ntstatus_dict = {}
for item in ntstatus_parsed.find_all('tr'):
cell = item.find_all('td')
if len(cell) == 0:
continue
code = cell[0].find_all('p')
description_ps = cell[1].find_all('p')
description_list = []
if len(description_ps):
for desc in description_ps:
if not desc.string is None:
description_list.append(desc.string.replace('\n ', ''))
else:
description_list = ['Description not available']
if not code[0].string.lower() in ntstatus_dict:
ntstatus_dict[code[0].string.lower()] = {"text": code[1].string, "desc": ' '.join(description_list)}
print(json.dumps(ntstatus_dict))
```
The second one is generating the code that is ready to be inserted into the
source file:
```
import json
ntstatus_file = open('ntstatus.json', 'r')
ntstatus = json.loads(ntstatus_file.read())
declaration_format = 'pub const SMB_NT%s:%su32 = %s;\n'
resolution_format = ' SMB_NT%s%s=> "%s",\n'
declaration = ""
resolution = ""
text_max = len(max([ntstatus[x]['text'] for x in ntstatus.keys()], key=len))
for code in ntstatus.keys():
text = ntstatus[code]['text']
text_spaces = ' ' * (4 + text_max - len(text))
declaration += declaration_format % (text, text_spaces, code)
resolution += resolution_format % (text, text_spaces, text)
print(declaration)
print('\n')
print('''
pub fn smb_ntstatus_string(c: u32) -> String {
match c {
''')
print(resolution)
print('''
_ => { return (c).to_string(); },
}.to_string()
}
''')
```
